  Note: for any given call to `subscribe` there must have been a previous call
  to `reg-sub`, registering the query handler (function) for the `query-id` given.

  #### Hint


  "Registers the given `interceptor` as a global interceptor. Global interceptors are
   included in the processing chain of every event.

   When you register an event handler, you have the option of supplying an
   interceptor chain. Any global interceptors you register are effectively
   prepending to this chain.
